Grapevine named ‘SV30-28-449’

ABSTRACT

A new and distinct variety of grapevine plant named ‘SV30-28-449’ particularly characterized by its ellipsoidal shaped, seedless black skinned berries which are large, sweet, slightly aromatic and have crisp texture. Productivity is moderate, with a mixture of spur and cane pruning required to achieve a full crop.

Latin name of the genus and species of the plant claimed: The plant claimed relates to a new and distinct variety of Vitis vinifera.

Variety denomination: The plant claimed shall be known as ‘SV30-28-449’.

STATEMENT OF ANY FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT

The present invention is not subject of Federally-sponsored research or development.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of grapevine botanically known as Vitis vinifera and hereinafter referred to as grapevine named ‘SV30-28-449’. As used herein, ‘grapevine’ refers to all plant parts including, vines, canes, tendrils, leaves, fruit and roots of grapevine named ‘SV30-28-449’. Grapevine named ‘SV30-28-449’ is the result of an effort to produce a mid-season black, seedless table grape with fruit characteristics superior to the currently available public cultivar ‘Unknown black’ (unpatented). This new cultivar originated from a cross conducted in May 2009 near McFarland, Calif. between seeded grapevine plant selection ‘SV22-88e-506’ (unpatented) and pollen parent ‘Princess’ (unpatented). Clusters of fruit resulting from the hybridization were harvested at maturity, the seeds collected and stratified for three months at 1° C. The seeds were then planted in a standard greenhouse flat and the seedlings grown in the greenhouse at 26.4° C. with 12 hours' illumination under high pressure sodium vapor lamps. The seedling population of 254 plants was planted in the field in the spring of 2010 near Delano, Calif. The new grapevine was selected from this seedling population on Aug. 27, 2012. It was then propagated by cuttings and bench grafted to ‘Freedom’ (unpatented) rootstock in 2013. The present invention has been found to retain its distinctive characteristics through two successive asexual propagations using woody cuttings.

Grapevine named ‘SV30-28-449’ differs from its female parent grapevine ‘SV22-88e-506’ (unpatented) in that grapevine named ‘SV30-28-449’ is seedless while female parent grapevine ‘SV22-88e-506’ (unpatented) has hard seeds.

Grapevine named ‘SV30-28-449’ differs from its male parent ‘Princess’ (unpatented) in that grapevine named ‘SV30-28-449’ has black skinned berries while male parent ‘Princess’ (unpatented) has green skinned berries.

Grapevine named ‘SV30-28-449’ differs from the commercial cultivar ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749) in that grapevine named ‘SV30-28-449’ has larger berries than ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749) and ripens in late August while ‘Sugrasixteen’ (U.S. Plant Pat. No. 11,749) ripens in mid-July. Grapevine named ‘SV30-28-449’ differs from commercial cultivar ‘Unknown black’ (unpatented) in that grapevine named ‘SV30-28-449’ has berries which are black with ellipsoidal shape while ‘Unknown black’ (unpatented) has reddish black berries which are cylindrical in shape.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the ripe fruit of this new variety when grown under normal horticultural practices near McFarland, Calif. Some of the characteristics may vary depending upon changes in crop load and change of location of cultivation.

-   -   1. Black berry color;     -   2. Very firm berry texture; and     -   3. Large, ellipsoidal shaped berries with sweet, aromatic taste.

BRIEF DESCRIPTION OF THE DRAWINGS

This new grapevine is illustrated by the accompanying photographs which show fruit clusters, leaves, canes, and tendrils. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The first photograph of shoots, leaves and a fruit cluster taken from a five year old plant grown in a field near McFarland, Calif. in 2018. The second photograph was taken in 2018 of a cluster of fruit on a three year old vine, grown in a field near Bakersfield, Calif.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of grapevine named ‘SV30-28-449’. Descriptions of the new invention apply to vines of grapevine named ‘SV30-28-449’ grown on ‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectare grown near McFarland, Calif. in 2018. These vines were in their fourth year of full production, having been planted in 2013. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere.
